" When SEALs sweep a building,” says Rich Davis, “slow is dangerous. We want to move as fast as possible. To do this, there are only two rules. The first is do the exact opposite of what the guy in front of you is doing—so if he looks left, then you look right. The second is trickier: the person who knows what to do next is the leader. We’re entirely nonhierarchical in that way. But in a combat environment, when split seconds make all the difference, there’s no time for second-guessing. When someone steps up to become the new leader, everyone, immediately, automatically, moves with him. It’s the only way we win. "
